The GIBRALTAR BBK-031-G is a brass ball knob with a threaded hole mount, designed for use as a hand-operated control knob on machinery, fixtures, jigs, and industrial equipment. The knob features a smooth grip surface and a natural brass finish. It accepts a 10-24 threaded stem with a hole depth of 0.375 inches, making it suitable for standard fastener engagement in light to medium-duty applications. At 0.75 inches in diameter, it provides a compact grip point where space is limited. Machinists, maintenance technicians, and equipment assemblers typically install this type of knob during machine setup or panel assembly work.
This ball knob is commonly used on machine tool controls, jig and fixture handles, cabinet hardware, and equipment adjustment points in manufacturing, industrial maintenance, and fabrication shop environments. The 10-24 thread size is a widely used standard, making this knob compatible with a broad range of threaded inserts, screws, and studs found in typical shop and panel applications. It is sold individually and suited for both OEM assembly and field replacement use.
Designed as a standard replacement or OEM-style threaded ball knob for machinery, fixtures, and equipment using 10-24 threaded hardware.
Installation requires no special tools beyond a mating 10-24 threaded stud or screw. Ensure the mating thread is clean and free of debris before threading the knob on. Hand-tighten to the appropriate position and verify secure engagement without over-torquing, which can damage brass threads. Power down or de-energize any equipment before replacing control knobs on live panels or machinery.
